摘要
基于跨区域贸易成本和通勤成本的视角,以2001-2019年259个城市为研究样本,利用双重差分模型研究高铁开通对城市技术创新的影响。研究发现:高铁开通实现技术创新的“增量提质”,显著提升城市的创新数量和创新质量;在同一经济带中,高铁开通对城市技术创新的影响具有异质性。
Based on the perspective of cross regional trade cost and commuting cost,by taking 259 cities from 2001 to 2019 as research samples,this paper analyzes the impact of the opening of high-speed rail on urban technological innovation by double difference model.Results show that the opening of high-speed railway improve the quantity and quality of technolog-ical innovation.The opening of high-speed railway significantly improves the innovation quantity and innovation quality of cities.And in the same economic belt,the impact of the opening of high-speed rail on urban technological innovation is heterogeneous.
